How this service works
Pay-per-call JSON tools for AI agents: Indian identifier validation (GSTIN, PAN, TAN, CIN, LLPIN, IFSC, PIN code, UPI ID, vehicle registration), AI-visibility (GEO) audits, AI crawler robots.txt matrices and llms.txt checks. x402 (USDC on Base) or RapidAPI.
Output
Returns a JSON object with: a boolean 'valid' flag, the 'detectedType' of identifier, a 'normalized' canonical form, a 'decoded' object containing identifier-specific metadata (e.g. state, state code, embedded PAN, checksum validity, PAN holder type for GSTIN), an 'errors' array listing validation failures, and a 'warnings' array for non-fatal issues. Blank or malformed inputs return a 400 error and are not charged.
Example use cases
GSTIN verification for GST compliance
“I need to verify this supplier's GSTIN before we process their invoice — can you validate 29ABCDE1234F1Z5 and tell me which state it's registered in and what type of entity holds this PAN?”
PAN card validation for KYC
“We're onboarding a new customer and need to validate their PAN number ABCDE1234F — is it valid and what type of PAN holder is it?”
IFSC code check before bank transfer
“Before I wire money, can you verify that the IFSC code HDFC0001234 is a real, valid bank branch code?”
Technical details
Endpoint
POSThttps://setu.xyz23110928.workers.dev/v1/india-id/validate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need lightweight, pay-per-call validation of Indian regulatory identifiers (GSTIN, PAN, TAN, CIN, LLPIN, IFSC, PIN code, UPI ID, vehicle registration) without integrating a heavy KYC SDK or government API. Ideal for AI agents performing real-time compliance checks, invoice processing, vendor onboarding, or financial workflows involving Indian entities. Supports auto-detection of identifier type so callers don't need to classify input upfront.
Side effects
- 400 Bad Request for blank or empty identifier values (not charged)
- Invalid checksum detected and reported in errors array
- Unknown or ambiguous identifier type when auto-detection fails
- Malformed value that doesn't match any known Indian identifier format
- Network/worker timeout on Cloudflare edge

| type | string | Force a type instead of auto-detection (default auto). Case-insensitive; one of: auto, gstin, pan, tan, cin, llpin, ifsc, pincode, upi, vehicle. |
| value | string | The identifier, e.g. 27AAPFU0939F1ZV. An optional "type:" prefix such as "pan:" is accepted; a PIN code may also be sent as a JSON number. Blank values are rejected (400, not charged). |
